SBM Distributor overhaul DIY?

Cool! I really appreciate your effort. I'm an engineer and can relate to graphs better then the written word.

Going to give the FBO plate a try. All the cool kids say its the schnizzel. It should help find the combo I like and then I can weld and file. Right now I just want a good, stable idle and reasonable drivability which shouldn't be too hard with the stock-ish 340 cam. I've got some more work to do on the body before I can commit to a serious build on the motor. Then I have to sell a kidney....
Hope to be able to put this in play tomorrow but I need to drive to Appleton and pick up some rear leaf springs.
